Introduction

When patients present with the complaint of a ‘funny turn’ it is usually possible to determine that they have one of the more recognisable presenting problems, such as fainting, ‘blackouts’, lightheadedness, weakness, palpitations, vertigo or migraine. However, there are patients who do present with confusing problems that warrant the label of ‘funny turn’. The most common problem with funny turns is that of misdiagnosis, so a proper and adequate history-taking is of great importance.

It is important to remember that seemingly ‘funny turns’ may be the subjective interpretation of cultural and linguistic communication barriers, especially in an emotional and frustrated patient.1 Various causes of faints, fits and funny turns are presented in Table 54.1. A useful simple classification is to consider them as:

The commonest cause of ‘funny turns’ presenting in general practice is lightheadedness, often related to psychogenic factors such as anxiety, panic and hyperventilation.2 Patients usually call this ‘dizziness’.

Absence attacks occur with minor forms of epilepsy and with partial seizures such as complex partial seizures.

The psychomotor attack of complex partial seizure presents as a diagnostic difficulty. The most commonly misdiagnosed seizure disorder is that of complex partial seizures or variants of generalised tonic–clonic seizures (tonic or clonic or atonic).

The diagnosis of epilepsy is made on the history (or video electroencephalogram [EEG]), rather than on the standard EEG, although a sleep-deprived EEG is more effective.
